PayPal 400 Demande incorrecte

Question

J'ai essayé d'implémenter une connexion via PayPal. Essentiellement, je viens de copier cet exemple: How to Implement User Log-in with PayPal. Cependant, j'obtiens une erreur 400 - Demande incorrecte pour la deuxième réponse (dans le fichier d'inclusion de connexion PayPal). Je ne peux pas faire beaucoup de l'erreur, peut-être que quelqu'un sait ce qui se passe. Le résultat:

Mon code: (ppinit.php définit simplement constantes)

require_once(dirname(__FILE__)."/ppinit.php"); 

$requestData = '?grant_type=authorization_code&code='.getGet("code").'&return_url=http://localhost/paypal/return'; 

$response = \Httpful\Request::get("https://" . PAYPAL_API_URL . "/v1/identity/openidconnect/tokenservice" . $requestData) 
->authenticateWith(PAYPAL_CLIENT_ID, PAYPAL_CLIENT_SECRET) 
->send(); 

$jsonResponse = json_decode($response->raw_body); 

if(isset($jsonResponse->error)) 
{ 
    echo "Fehler bei der Anmeldung mit PayPal."; 
    echo "<br/>"; 
    exit; 
} 
//that's the one that does not work. 
$response = \Httpful\Request::get("https://" . PAYPAL_API_URL . "/v1/identity/openidconnect/userinfo/?schema=openid") 
->contentType("application/json") 
->authorization($jsonResponse->access_token) 
->authenticateWith(PAYPAL_CLIENT_ID, PAYPAL_CLIENT_SECRET) 
->send(); 
$ppuser = json_decode($response); 

Answer 1

D'une manière générale, un HTTP 400 Bad Request signifie que la requête envoyée était malformé-à-dire le flux de données envoyé par le client au serveur n'a pas suivi les règles - read more.

Il est difficile de dire la source exacte de telles erreurs car il pourrait y en avoir beaucoup, mais je vous suggère d'encapsuler vos appels HTTP dans des blocs try/catch et de rechercher la cause de l'erreur. Donc, dans ce cas, vous pouvez remplacer votre code avec ceci:

try { 
    $response = \Httpful\Request::get("https://" . PAYPAL_API_URL . "/v1/identity/openidconnect/tokenservice" . $requestData) 
     ->authenticateWith(PAYPAL_CLIENT_ID, PAYPAL_CLIENT_SECRET) 
     ->send(); 
} catch (Exception $e) { 
    var_dump($e->getMessage()); 
    exit(1); 
} 

Si vous utilisez l'espace de noms mis un \ avant Exception ->\Exception

Answer 2

Remplacement de la deuxième demande avec le code ci-dessous œuvres.

try 
{ 
    $params = array('access_token' => $jsonResponse->access_token); 
    $userInfo = OpenIdUserinfo::getUserinfo($params, $paypal); 

} catch (Exception $ex) 
{ 
    echo $ex; 
    exit(1); 
}
